To aZZ whom it may concern.'

Be it known that I, JAMES T. CoxEN, a citiz en of the United States,residing at Sidburn, in the county of Fairfax and State, of Virginia,have invented new and useful Improvements in Spring-Motors, of which thefollowembodying an auxiliary spring for actuating motor constituting thepresent and preferred a fan or other extraneous device, and a connectionintermediate the device that is vibrated and the said auxiliary springfor placing and maintaining the latter under tension while the motor isin operation, and thereby rendering it unnecessary for the operator towind said auxiliary spring,

Other advantageous features of the invention will be fully understoodfrom the following descriptionand claims when taken in connection withthe accompanying drawings, formlng part of this speclfication, in which-Figure l -is a side elevation illustrating the embodiment of myinvention as connected to a spring-supported'body to be vibrated. Fig.2, is an enlarged vertical section of the novel motor per se, thepallet-lever of'said motor being shown by full lines in its idle'position and by dotted lines in its active position. Fig. 3 is atransverse'section taken in theplane indicated by the line 3 3 of Fig.2, and Fig. 4 is a detail section illustrative of the auxiliary springand the appurtenances thereof. Fig. 5 is a detail view illustrating therelative arrangement of one of the side' plates of the main frame, theperimeter of one of the springhousings, and one of the lateral armsfor-connecting the latter to the former.

Similar letters designate corresponding parts in all of the views of thedrawings, referring to which- A is a spring-supported device, preferablythe spring-supported body of a baby-carriage.

B is my novel motor as a whole, and C is the support on which the motoris mounted. The said support when the motor is used in connection withthe spring-supported body of a baby-carriage may be and preferably isformed by the frame of the carriage.

As best shown in Figs. 2 to 4 of the drawings, the motor comprises aframe having side plates a; circular housings b, arranged at the outersides of the said plates and connected thereto through the medium oflateral arms o, fixedly connected to the side plates and the perimetersof the housings; a transverse primary shaft OZ, journaled in the sideplates and extending into the housings, Fig. 3; spurgears e, fixed onthe shaft Z and interposed between the inner edges of the housings b andthe outer sides of the frame-plates af a transversel shaft f, journaledin the said frameplates and having pinions g intermeshed with the gearse and also having, by preference, an angular end 7L to receive a crankorother device for turning the shaft; coiled springs c', nested in thehousings and connected at one end to the shaft oZandiat their oppositeends tothe housings b; a ratchet-wheel j, fixed` through the medium of aset-screw or other means, on the shaft d; a spur-gear Z, loosely mountedon the shaft d alongside the ratchet- Wheel j and carrying one or. aplurality of nected by one or more gears with the shaft d,

preferably through the medium of a gear 2o and the before-described gearZ, anda toothed 'wheel g, fixed on the shaft a and forming part of anescapernent/which 1 will now describe. In addition to the toothed wheelq the said escapement comprises a lever e, fulc'rumed .at a so as tooscillate vertically; a pallet arranged on the short arm of the leverand hav- Aingends which alternately engage with teeth at o pposite sidesof a line extending diametricallyacross'the toothed wheel q; ashaft o',journaled in .the frame; an arm d, fixed on one end of the shaft andhaving a lateral projectione arranged to be thrown into and out ofengagement with the lever z after the mannershownby full and dottedlines, respectively, in Fig. 2, and anlarm f', fixed on the opposite endof the shaft c and having a projection g', the said projection g beingadapted when the lever or arm f is sprung'away from an upright it on theframe to be moved across the face of said upright and engaged with theIlO IOO

opposite vertical edges thereof. By reference to Fig. 2 it will be seenthat when the projection g is in the position shown by full lines at oneedge of the upright 7L' the projection e on the arm d' will bear on thepalletlever z and lock the same against oscillation or other movement,while when the said lug or projection g is in the position shown bydotted lines the lug or projection e will'be secured out of engagementwith the lever e, so as to leave the latter free to oscillate under theaction of the springs t'.- By springing the lever f laterally away fromthe upright t the lug g may be readily disengaged from either edge ofthe said upright, and the lever may then be moved from the positionshown by full lines in Fig. 2 to that shown by dotted lines, and viceversa.

D is 'a connection, preferably a link, which is interposedbetween andconnected to the long arm of the lever 2 and the spring-supported deviceA. The said connection D is designed when the motor is in operation torapidly move the device A up and down. This movement of the device Awhen the said device is the spring-supported body of a baby'- carriagewill obviously amuse and tend to lull a child i-n the body to sleep.

r is a transverse shaft journaled in the frame-plates a and bearing agear-wheel s. t is a ratchet-wheel loosely mounted on said shaftadjacent to one of the frame-plates.

u is a pawl connected to one of the frameplates and engaging the teethof the wheel t, so as to hold the latter against retrograde movement.

c is a spring coiled about the shaft r and connected at one end to thewheel t and at its opposite end to the shaft r.

w is a bar pivotally connected to the springsupported device A andguided by means on one of the frame-plates a.

is a dog carried by the bar w and arranged to engage the teeth of thewheel t on the downward movement of the bar and to ride idly over saidteeth on the upward movement of the bar, and a3 is a dog mounted betweenthe frame-plates ct and adapted in the position shown by full lines inFig. 2 to hold the gear s against rotation and in the position shown bydotted lines in said figure to permit rotation of said gear.

Incident to the up-and-down movements of the device A the bar w will berectilinearly reciprocated, and the dog carried thereby will rotate theratchet-wheel t step by step, with the result that the spring 'u will beplaced under tension. The gear s is designed to be connected with a fanor other rotary device, (not shown,) and hence it Will be observed thatwhen the dog a is disengaged from the gear .sj the contracted spring e'may be utilized to rotate said rotary fan or device. In virtue of thislatter construction it will be observed that the necessity of theoperator winding the spring e at intervals is obviated, which is animportant desideratum.

As will be readily appreciated by reference to Fig. 3, the arrangementof the mainsprings a' in the rhousings and the interposition of thegears e between the inner edges of the housings and the outer sides ofthe frameplates @render the construction compact and strong and durable;also, that the shaft f, pinions g, and gears e enable the operator toexert great leverage in winding the shaft d for the purpose of windingor placing the mainsprings under tension.

I have specifically described the construction and relative arrangementof the parts in the present and preferred embodiment of my invention inorder to impart a definite understanding of the said embodiment. I donot desire, however, to be understood as confining myself to the saidspecific construction and relative arrangementof parts, as such changesor modifications may be made in practice as fairly fall within the scopeof my invention as claimed.

Having described my invention, what I claim, and desire to secure byLetters Patent, is-

l. In a spring-motor the combination of a suitable frame, a shaftjournaled therein, one or more springs for rotating said shaft, anescapement comprising atoothed wheel mounted in the frame, a lever alsomounted in the frame, and a pallet carried by the lever and having endsarranged to alternately engage a tooth of the wheel, a drivingconnection intermediate the spring-actuated shaft and the toothed wheelof the escapement, a bar fixed with respect to the frame, a shaftjournaled in the said bar, an arm carried by said shaft and arranged tobe moved into and out of engagement with the lever of the escapement,and an arm carried by the shaft and having a projection adapted to besprung into and out of engagement with the opposite edges of the bar.
